[0033] like Figure 1As shown, the present application discloses a power system distribution network operation monitoring device, which includes a monitoring device body 1, a movable cover plate 2, a first rotating assembly 3, a mobile assembly, a second rotating assembly 4 and a transmission antenna 5. The monitoring device body 1 is a device for monitoring the voltage, current and surrounding environment of the distribution network operation. The monitoring device body 1 collects monitoring data fed back by various sensors and remotely transmits the monitoring data to the monitoring center, so that the monitoring center can collect data, make analysis and early warning, and ensure the normal operation of the distribution network. In order to ensure the quality and efficiency of data transmission, the existing devices all use external antennas. However, the external antennas are greatly affected by the environment and are exposed to the outside for a long time. They are easily attacked by various bad weather and affect their service life. Therefore, in order to ensure the stability and durability of data transmission, the present application effectively protects the external antenna through the following technical solutions.

[0034] like Figure 1-2 As shown, a storage slot 6 is provided on the monitoring device body 1, and a first rotating assembly 3 is provided on one side of the slot of the storage slot 6. One end of the movable cover plate 2 is connected to the first rotating assembly 3. The first rotating assembly 3 is used to drive the movable cover plate 2 to rotate, so that the movable cover plate 2 can contact or move away from the storage slot 6 by rotating. When the movable cover plate 2 contacts the storage slot 6, the movable cover plate 2 covers the slot of the storage slot 6, and one side thereof faces the storage slot 6. A moving assembly is provided on one side of the movable cover plate 2 facing the storage slot 6, and the transmission antenna 5 is rotatably connected to the moving assembly through the second rotating assembly 4. The moving component is used to move the transmission antenna 5, and the second rotating component 4 is used to drive the transmission antenna 5 to rotate. When the transmission antenna 5 needs to be used and the movable cover 2 is opened, the transmission antenna 5 is rotated so that the transmission antenna 5 and the movable cover 2 are in a vertical state, and the transmission antenna 5 can be used to receive or transmit signals; when the transmission antenna 5 is not needed to transmit data, the transmission antenna 5 is rotated so that the transmission antenna 5 is parallel to the movable cover 2, and then the movable cover 2 is rotated so that the transmission antenna 5 is stored in the storage groove 6, thereby completing the storage of the transmission antenna 5 and realizing the protection of the transmission antenna 5.

[0035] Specifically, in order to facilitate the control of the rotation of the movable cover plate 2, in this embodiment, the first rotating assembly 3 includes a first rotating motor, a driving gear, a transition gear, a driven gear and a rotating shaft. The output end of the first rotating motor is connected to the driving gear, the driving gear is meshed with the transition gear, the driven gear is meshed with the transition gear, the driven gear is sleeved on one end of the rotating shaft and connected to the rotating shaft, and one end of the movable cover plate 2 is connected to the rotating shaft. The driving gear is driven by the first rotating motor to rotate, and the driving gear drives the transition gear to rotate. After the transition gear is driven, the driven gear is driven to rotate, so that the rotating shaft rotates, and then the rotating shaft drives the movable cover plate 2 to rotate, so that the movable cover plate 2 contacts or moves away from the storage slot 6, which is convenient for the use and storage of the transmission antenna 5. The transition gear is added between the driving gear and the driven gear to increase the transmission torque, which is convenient for the precise control of the rotation angle of the movable cover plate 2.

[0036] Specifically, in order to facilitate the adjustment of the position of the transmission antenna 5 and to facilitate the storage or use of the transmission antenna 5, in this embodiment, the moving assembly includes a screw rod 7, a screw rod 7 motor and a moving block 8. The screw rod 7 is fixedly connected to the output end of the screw rod 7 motor. The moving block 8 is arranged on the screw rod 7 and is threadedly connected to the screw rod 7. The second rotating assembly 4 is arranged on the moving block 8. The second rotating assembly 4 includes a second rotating motor 41, a transmission gear 42, a transmission belt 43, a synchronous gear 44, a rotating rod 45 and an angle sensor 46. The output end of the second rotating motor 41 is fixedly connected to the transmission gear 42. The transmission gear 42 is connected to the synchronous gear 44 through the transmission belt 43. One end of the rotating rod is fixedly connected to the synchronous gear 44. The angle sensor 46 is connected to one end of the rotating rod away from the synchronous gear 44. The transmission antenna 5 is connected to the rotating rod 45. The angle sensor 46 is connected to the rotating rod 45. The angle of rotation of the rotating rod 45 can be detected by the angle sensor 46, so that the rotation angle of the transmission antenna 5 can be known, so as to facilitate the accurate control of the angle of the transmission antenna 5.

[0037] When the transmission antenna 5 is needed to transmit data, after the movable cover 2 is adjusted, the transmission gear 42 is driven to rotate by the second rotating motor 41, and the transmission gear 42 drives the synchronous gear 44 to rotate through the transmission belt 43, and the synchronous gear 44 then drives the rotating rod 45 to rotate. The transmission antenna 5 is set on the rotating rod 45, and then the transmission antenna 5 is rotated to make the transmission antenna 5 change from a state parallel to the movable cover 2 to a state perpendicular to the movable cover 2, and the transmission antenna 5 can be used to transmit data. When the transmission antenna 5 is not needed to transmit data, similarly, by adjusting the angle of the transmission antenna 5, the transmission antenna 5 is changed from a state perpendicular to the movable cover 2 to a state parallel to the movable cover 2. If the end of the transmission antenna 5 exceeds the boundary of the movable cover 2 at this time, it can be adjusted by the moving component until the movable cover 2 completely covers the transmission antenna 5, and then the movable cover 2 is rotated to make the movable cover 2 contact the storage slot 6, and the transmission antenna 5 is stored in the storage slot 6 to protect the transmission antenna 5.

[0038] like Figure 2 As shown, in order to solve the problem that the existing external antenna used outdoors always consumes power when not in use, in this embodiment, the transmission antenna 5 includes an antenna connection base 51, a threaded connector 52 and a transmission antenna body 53. The antenna connection base 51 is fixedly connected to the rotating rod 45, the threaded connector 52 is arranged on the antenna connection base 51 and connected to the antenna connection base 51, and the transmission antenna body 53 is threadedly connected to the threaded connector 52. The antenna connection base 51 is connected to the PCB board in the monitoring device body 1, and serves as a device for data and electrical connection with the controller on the PCB board. The threaded connector 52 serves as a device for electrical connection between the antenna connection base 51 and the transmission antenna body 53, so that the transmission antenna body 53 is electrically connected while being threadedly connected to the threaded connector 52, thereby realizing the data transmission function. When the transmission antenna 5 is stored in the storage slot 6, a disassembly component is arranged in front of the transmission antenna 5, and the transmission antenna 5 is disassembled by using the disassembly component to reduce the power loss of the transmission antenna 5.

[0039] Specifically, the disassembly assembly includes a cylinder body 9, a rotating body 10, a cylinder split body 11, and a cylinder clamp 12 for clamping the transmission antenna 5 body. The rotating body 10 is arranged on the cylinder body 9, and one end of the rotating body 10 away from the cylinder split body 11 is connected to the cylinder split body 11, and the output end of the cylinder split body 11 is connected to the cylinder clamp 12. When the transmission antenna 5 is stored, the end of the transmission antenna 5 body is moved to the cylinder clamp 12 by the moving assembly, and the cylinder split body 11 is controlled to drive the cylinder clamp 12 to clamp the transmission antenna 5 body, and then the cylinder body 9 is controlled to drive the rotating body 10 to rotate, so that the transmission antenna 5 body rotates until the transmission antenna 5 body is separated from the threaded connector 52, and the transmission antenna 5 body can be removed from the threaded connector 52, thereby reducing the energy consumption of the transmission antenna 5.

[0040] Furthermore, in order to prevent water from accumulating in the storage slot 6 and affecting the service life of the transmission antenna 5, in this embodiment, a flow guide pipe is provided in the monitoring device, the flow guide pipe is provided in the monitoring device body 1, a flow guide hole is provided at the bottom of the storage slot 6, one end of the flow guide pipe is connected to the flow guide hole, the flow guide pipe is communicated with the storage slot 6, an outflow hole is provided on the outer surface of the monitoring device body 1, one end of the flow guide pipe away from the flow guide hole is connected to the outflow hole, and the flow guide pipe is communicated with the outside. When water accumulates in the storage slot 6, the water in the storage slot 6 is discharged by the flow guide pipe to prevent excessive water accumulation from affecting the transmission antenna 5.

[0041] Furthermore, in order to prevent dust and other tiny substances from entering the storage tank 6 through the guide tube, as Figure 4 As shown, in this embodiment, a check valve structure is provided in the guide pipe, and the check valve structure is used to conduct one-way conduction of the accumulated water in the storage tank 6, so as to prevent external dust from entering the storage tank 6 from the guide pipe. Specifically, the check valve structure includes a fixed pipe body 13, a fixed base 14, a baffle 15 and a spring 16, the fixed pipe body 13 is fixedly connected in the guide pipe, the fixed base 14 is fixedly connected to the middle of one end of the fixed pipe body 13, a convex edge is provided on the end of the fixed pipe body 13 away from the fixed base 14, the baffle 15 is provided on the inner side of the convex edge and abuts against the convex edge, one end of the spring 16 is connected to the fixed base 14, and the other end is connected to the baffle 15.

[0042] The elastic force of the spring 16 is used to make the periphery of the baffle 15 abut against the tube opening of the fixed tube body 13, closing the fixed tube body 13. When there is water accumulation in the storage tank 6, the accumulated water falls from the guide tube to the baffle 15 due to gravity, and the spring 16 is compressed to make the baffle 15 away from the tube opening of the fixed tube body 13, and a gap appears between the baffle 15 and the tube opening of the fixed tube, and water flows out from the gap. When there is no water accumulation or less water accumulation in the storage tank 6, the baffle 15 abuts against the tube opening of the fixed tube body 13, and dust cannot enter the storage tank 6 from the guide tube, thereby reducing the impact of dust on the storage tank 6 and the transmission antenna 5.

[0043] The working principle of the utility model is as follows: when the transmission antenna 5 needs to be used to transmit data, the first rotating component 3 is used to drive the movable cover plate 2 to rotate, and the movable cover plate 2 is away from the storage slot 6 until the movable cover plate 2 is parallel to the horizontal plane, so that the movable component, the second rotating component 4 and the transmission antenna 5 are all facing upward, and then the second rotating component 4 drives the transmission antenna 5 to rotate, so that the transmission antenna 5 changes from a state parallel to the movable cover plate 2 to a state perpendicular to the movable cover plate 2, and the transmission antenna 5 can be used to receive or send signals;

[0044] When the transmission antenna 5 is not needed for data transmission, the transmission antenna 5 is driven to rotate by the second rotating component 4, so that the transmission antenna 5 changes from a state perpendicular to the movable cover 2 to a state parallel to the movable cover 2, and then the movable cover 2 is driven to rotate by the first rotating component 3 until the movable cover 2 contacts the storage groove 6, completing the storage of the transmission antenna 5 into the storage groove 6, and then the moving component is controlled to move one end of the transmission antenna body 53 of the transmission antenna 5 to the disassembly component, and the disassembly component is used to remove the transmission antenna 5 body from the antenna connection base 51, so as to realize the disassembly of the transmission antenna 5 and reduce power loss.
